标准摘要
[中文适用范围]: 本技术报告描述了两种测量单模光纤对弯曲处高功率损伤敏感性的方法:方法 1-失效时间表征,作为发射功率和弯曲条件(弯曲角度和直径)的函数;方法 2-平衡温度测量。两种方法的结果只能定性比较。本报告中的结果主要针对未缆化和未缓冲的光纤。缆化和缓冲的光纤预期会有不同的响应,因为外层会影响老化过程。请注意,方法 2 测试不适用于缓冲或缆化光纤。这些方法不构成用于评估光纤的常规测试。从这两种方法导出的参数并不打算在详细的光纤规范中指定。本文档中描述的一般发生在弯曲半径远小于单模光纤规范 IEC 60793-2-50 中规定的半径,或仅基于机械可靠性考虑所推荐的半径下的灾难性失效模式。本报告包含几个附件,包括对所采用方法的原理、评估指标、指南、示例以及初步研究的一些结论的讨论。 [外文原描述]: IEC/TR 62547:2013(E) describes two methods for the measurement of the sensitivity of single-mode optical fibres to high-power damage at bends: - test method 1 - Failure time characterisation as a function of the launch power and bend conditions (bend angle and bend diameter); - test method 2 - Equilibrium temperature measurement. Results from the two methods can only be compared qualitatively. This second edition cancels and replaces the first edition published in 2009, and constitutes a technical revision. The main changes with respect to the previous edition are: - updates related to B6 (bend-insensitive) category single-mode fibres); - update to analysis for test method 2: Maximum temperature specification. Key words: sensitivity of single-mode optical fibres to high-power damage at bends
